Doubling Season doubles Tyvar Kell's entering loyalty from 3 to 6, letting him cash out his ultimate immediately, die as a state-based action, and leave behind the emblem. From there, Cloudstone Curio bounces one elf when the other enters, and each cast draws two cards off the emblem — the green elf engine common to Golgari superfriends and dedicated Tyvar builds.

Variations

Cheaper, tighter, alternate lines

Any two distinct one-drop elves that produce green mana can substitute for Llanowar Elves and Fyndhorn Elves — Elvish Mystic is the obvious third piece that makes the bounce chain redundant as an additional starter. The loop draws the whole library but doesn't close on its own; add Thassa's Oracle or Finale of Devastation as the kill, since the combo itself stops at infinite cards and storm count.
